Lightmap rendering (and perhaps other elements w/ alpha) sporadically turns pitch black, depending on the hardwares #8

Now everything--blocks, actors, UIs--are rendered black. Tested with my low-end rig that has 9800 GT, Intel E8400, 4GB RAM.

At least for the black lightmap, now recent nVidia driver also breaks it (although sporadically), clearly it's my code that is shit.

And when lightmap is not rendering, framerate is like 800; normally it's 80.

Half frame trick (update only when global render timer is odd/even) was the culprit, sometimes it would not increment; fixed along with feature implementation (faster blocks and lightmap draw) by simply removing the trick.
